Öğe Effects of Fiber-rich Apple and Apricot Powders on Cookie Quality(Korean Society Food Science & Technology-Kosfost, 2009) Seker, Ibrahim T.; Ozboy-Ozbas, Ozen; Gokbulut, Incilay; Ozturk, Serpil; Koksel, HamitApple and apricot powders (APL-P and APR-P) were produced from apple and apricot fruits and they were used in cookie formulation at the levels of 10-40% (in flour bases). The APL-P and APR-P were rich in terms of total dietary fiber (TDF) and antioxidant power. The APR-P supplemented cookies had higher spread ratio and lower hardness values than the APL-P supplemented ones at all addition levels. The color values of the APR-P supplemented cookies were all acceptable. Overall sensory scores of the cookies supplemented with APL-P and APR-P were not significantly different from the control up to 20% addition. TDF contents of the supplemented cookies increased significantly with increasing addition level (p<0.01). The replacement Of flour by APL-P and APR-P in wire-cut cookies showed that the physical characteristics and textural properties of the cookies were significantly affected (p<0.01) and APR-P appeared to be a more suitable replacer of flour than APL-P. Addition of both fruit powders upto 20% into the cookie formulation were evaluated as acceptable in terms of the sensory properties.Öğe Utilization of brewer's spent grain in the production of Frankfurters(Wiley, 2009) Ozvural, Emin Burcin; Vural, Halil; Gokbulut, Incilay; Ozboy-Ozbas, OzenThe effects of dried and ground brewer's spent grain (BSG) on dietary fibre content and some quality characteristics of beef Frankfurters were investigated. BSG preparations of fine (< 212 mu m), medium (212-425 mu m) and coarse (425-850 mu m) particle sizes were used in the production of Frankfurters. The total dietary fibre (TDF) content of the Frankfurters supplemented with BSG of different particle sizes increased significantly (P < 0.05) as the level of addition was increased. The mean TBA (2-thiobarbituric acid), colour and texture values except springiness had significant differences (P < 0.05) among the treatments. The overall acceptability scores for the control and the Frankfurters with BSG were 7.57 and 5.47-7.02 on a nine-point scale, respectively. Cluster analysis was also carried out to divide the measured parameters into clusters according to their similarities and to find out the correlations among them. It can be concluded that BSG can be added to Frankfurters to increase their fibre content without deleteriously affecting their sensory parameters.Öğe Utilization of sugarbeet fiber and brewers' spent grain in the production of tarhana(Verlag Dr Albert Bartens, 2010) Ozboy-Ozbas, Ozen; Hancer, Ayla; Gokbulut, IncilayIn this study, the effects of sugarbeet fiber (SBF) and brewers' spent grain (BSG) on the quality of tarhana, a fermented wheat flour-yoghurt product, were studied. SBF was produced from sugarbeet pulp collected after pressing. BSG was a malt-rice adjunct mash spent grain. SBF and BSG of particle sizes >425 mu m were added into the tarhana formulation at levels of 3, 6, 9, and 12%. Total dietary fiber (TDF) contents of SBF and BSG were 72.9% and 65.2%, respectively. Chemical properties, color values, sensory scores and TDF contents of SBF- and BSG-containing tarhana samples were investigated. Addition of SBF decreased protein and crude fat values but BSG increased them significantly (p < 0.01). Addition of SBF and BSG resulted in lower L*a*b* color(1) values giving slightly darker products. The TDF contents of organoleptically accepted 9% SBF and 6% BSG added tarhanas showed 3 and 2 fold higher TDF than the control groups, respectively. Utilization of SBF and BSG in tarhana production resulted in acceptable soup properties in terms of most of the sensory properties. Slightly lower values in some of the sensory properties (color, odor, and taste) could be compensated by the health benefits of fiber products.Öğe Utilization of sugarbeet fiber and zero-trans interesterified and non-interesterified shortenings in cookie production(Verlag Dr Albert Bartens, 2008) Ozturk, Serpil; Ozboy-Ozbas, Ozen; Javidipour, Issa; Koksel, HamitIn this study, the effects of sugarbeet fiber (SBF) and non-interesterified (non-in-es) and interesterified (in-es) cottonseed oil (CO), palm oil (PO) and CO:PO blend on the quality of cookies were studied. SBF of particle size >425 mu m was added into the cookie formulation at the levels of 5, 10, 15, 20, and 25%. The addition of SBF significantly increased (p < 0.05) the total dietary fiber (TDF) content of cookies. Incorporation of non-in-es and in-es CO and CO:PO improved the nutritional content of the product by altering the fatty acid composition. These experimental shortenings have zero-trans fatty acids and considerably higher linoleic acid than hydrogenated shortenings. The in-es PO and in-es CO:PO blends had lower solid fat contents than their non-in-es counterparts and this resulted in higher spread ratios in in-es shortening incorporated cookies. Favorable cookies, similar to the standard cookies with modified fatty acid compositions and similar to 4 fold higher TDF, have been made by using non-in-es and in-es CO and CO:PO with 15% SBF, without significantly adverse changes in sensory properties.
